25-286 and 25LS. The models 50 and 60 were also 286s'
The models up to (but not including) the 50 series were ISA and after microchannel. The 25 came out originally as an XT
class machine with an
8086
processor ( see
http://www.can.ibm.com/helpware/8525.html ) and the 286
version of
it was only one version that I'm aware of as seen
at

The LS may be an aftermarket version, much like putting a Reply
motherboard into
one.
All the info on the vintage IBM machines can be found starting with the
index page

Thanks for the reference. I have bookmarked it.
Thanks also to everyone who has pointed out the model 25 and the 286
versions. Both well after my time - when I left IBM there were just the
30, 50, 60 and 80. I think I had heard of the 25 though - perhaps that
will teach me not to open my mouth quite so wide.
No thanks to whoever said the 8088 and 8086 were the same thing. If that's
the case, the Pentium and the 80386 are the same thing :-)
